What is the history of Binchotan charcoal?The origins are not completely clear, but it is believed that a form of Binchotan charcoal (sometimes referred to as 'white charcoal') was introduced to Japan by a Japanese monk and scholar called Kukai 1,200 years ago. It was during the Edo Period (17th century) that a man called Binchuya Chozaemon made it popular.

How is it made?Sustainably sourced wood is placed in a kiln and charred at a relatively low temperature for some time, then, near the end of the process, the kiln temperature is raised to about 1000 degree Celsius to make the wood red-hot. The charcoal is then removed and quickly covered with a special powder made from earth, sand and ash, and this gives the charcoal surface a whitish hue (explaining the name 'white charcoal'). The rapid rise in temperature, followed by a rapid cooling, incinerates the bark and leaves a smooth, hard surface. If you strike it, you'll hear a clear, metallic sound.

How does it work?Binchotan charcoal has an incredibly porous surface with tiny cavities oriented in many directions. Just 1 gram has a surface area in excess of 500 m2 (about one tenth the size of a football field). It is also known as active carbon as the ions of contaminants are attracted to the surface of the carbon, where they will be held. It is also able to release minerals such as calcium, iron and magnesium back into the water which enhances its taste and health benefits.

How long will it last?If you are using your Binchotan with our 'eau good' bottle and fill it up once a day, then it should last three months. You are then able to recharge it by boiling it in water for ten minutes and then leaving to dry in sunlight. You should be able to keep recharging it for a further three months.

What other uses does the binchotan have?When you have finished using your binchotan as a water filter, it still has many secondary uses. If you break it up and put it in your house plants, it will add nutrients to the soil that will help the plant to grow. Because of its porous surface, it can be used as a deodoriser to remove unwanted odors in your cat litter, laundry basket, nappy bin or shoes. Binchotan is also an effective moisture absorbent, and can help absorb humidity in the air if placed in a wardrobe.

Do I need to wash my charcoal?Your binchotan charcoal is already washed and ready to use. Please do not wash with detergent or soap.

Can I use my binchotan with flavoured water (fruit infused or tea)?Please do not use with flavoured cordials, fruit infusions or tea.

Can I wash my bottle with soap and leave the charcoal in it?Please remove the binchotan from the bottle before washing with soap.

Where can I order more charcoal from?Order from our website or on amazon.

Is it dangerous if I swallow a bit of charcoal?Occasionally you will notice tiny particles / fragments of the charcoal in the water, but do not be alarmed as it will do you no harm if you swallow them (active charcoal tablets are prescribed to treat diarrhoea, indigestion and flatulence).

How should I clean my bottle?We advise to wash this by hand with hot soapy water and a bottle brush. Although the bottle and metal clamp are dishwasher safe, the fabric tag will not withstand frequent dishwashes. The silicon seal on the cork can be removed and is dishwasher safe. The cork is not dishwasher safe.

How do I prevent mould from forming on the silicone covering the cork stopper?Make sure you do not leave water sitting in your bottle, when you are not using it (for more than one day). Remove the stopper and allow it dry out. When water is left in the bottle for long periods of time, mould spores can form. The binchotan charcoal removes the chlorine from drinking water, so you might notice it forming even quicker than normal. This is nothing to worry about, as long as you are refilling regularly, cleaning the bottle regularly and not drinking stale water that has been sitting in the bottle for more than a day.

How do I clean mould from the silicone covering the cork stopper?We recommend using neat lemon juice, followed by boiling water, to kill and wash away mould that has formed on the silicone.

Features

Leak proof natural cork &

silicone seal

The natural cork and silicone stopper is held securely in place by the reassuring stainless steel ring, so there is no danger of the bottle leaking in your bag. Also, the fabric loop makes it easy to carry your bottle while on the go and it also helps you pull the stainless steel ring to secure the stopper.

Simply drop & lock your charcoal

The bottle is specially designed to hold the Binchotan charcoal securely in place. Simply drop, squeeze, tilt and lock, to prevent it moving inside the bottle. The charcoal is an organic product, so the thickness can vary. PLEASE NOTE: The important thing is that the charcoal locks in place, even if it appears to be only barely inside the groove. If you force the charcoal into the space, you can cause the bottle to crack.

Ergonomic Form

The curvaceous shape of the bottle, gives a natural position for your hand and makes it comfortable and reassuring to hold.

No 7 on the bottle

The bottle is made from Tritan™, produced by the American company Eastman. Tritan™ is absolutely BPA free and of the very highest standards, passing the strictest regulations.
Having a recycling number does not determine what the material is made from - it is only there to instruct the user how to recycle the material.

Introducing Binchotan charcoal

Why use binchotan

Charcoal?

It may seem counter intuitive to purify your drinking
water with a stick of charcoal, but the Japanese have
been doing it for centuries.
Binchotan is an active carbon made from tree branches
and is renowned for its ability to soften water, add good
minerals and absorb unwanted tastes and odours, such
as chlorine.

How does it work?

Your charcoal is ready to use. Simply fill your bottle/carafe with
drinking (potable) tap water and wait for the charcoal
to filter impurities from the water. Leaving it overnight
is ideal, but you will taste the difference after just one
hour. Then, enjoy great tasting water!
You can use the charcoal in our EAU CARAFE, or any bottle for that matter. Wait for the charcoal to filter the water overnight is ideal, but you will taste the difference after just one hour. Then, enjoy great tasting water!

How long does it last?

With time, you will notice a decrease in the filter’s effectiveness on the water taste.
You can then recharge it by simply boiling it for ten minutes. The boiling washes out the impurities and frees the charcoal up to absorb some more. Some people have more sensitive taste buds than others so if you notice the decline in taste before 3 months has passed, then it is absolutely fine to boil it at that stage too. Giving it a total life span of six
months, as long as it delivers the desired effect, it means it is working!

Broken charcoal?

It still works just the same! Not sure? Well, if you want to know more about Binchotan such as where it comes from and what you can do with it at the end of its life, please see the FAQ tab at the top of this page.
